2 CZ-EMM3 CZ-EMM4 SATEL
Design
The electronic circuit is potted in epoxy resin for protection against moisture and dust. The
multi-conductor cable is led-out of the reader enclosure.
Data format
The reader can transmit data using one of the formats below:
EM-Marin (used for communication with the SATEL devices)
Wiegand 26
Clock & Data
You can select the data format during configuration of the reader.
Signaling
The LED indicators and audible signal are controlled by the device the reader is connected
to. When configuring the reader, you can define whether the signaling control inputs are to be
high level (5...12 V) or low level (0 V) sensitive.
The reader has two LEDs: red and green.
Bell key [CZ-EMM4]
The bell key controls directly the BELL output of the reader. The BELL output is an OC type
low-current output. Pressing the key will short the output to the common ground.
3. Installation
The device should be installed by qualified personnel.
Disconnect power before making any electrical connections.
The detector can be installed indoors as well as outdoors.
If the reader is installed on a metal surface, the card reading range will be reduced.
Two readers connected to the same device can work when situated a short distance
from each other. However, the distance from a reader connected to another device or
a device with built-in reader (e.g. a keypad with reader) should be at least
50 centimeters.
If you need an extra cable to make the connections, use an unshielded non-twisted cable.
The total length of the cable connecting the reader to the device should not exceed
30 meters.
1. Open the reader enclosure.
2. Place the enclosure base against the wall and mark the location of mounting holes.
3. Drill holes for wall plugs (anchors) in the wall.
4. Make a hole in the wall for the reader cable and run the cable through it.
5. Using wall plugs (anchors) and screws, secure the enclosure base to the wall. Select wall
plugs specifically intended for the mounting surface (different for concrete or brick wall,
different for plaster wall, etc.).
6. Close the enclosure and secure it with the screw.
7. If the reader is NOT to be connected to a SATEL device, configure the reader settings
(see “Configuring” p. 3).
